The locos are painted with cellulose paint. In general 2 coats of undercoat and 5-6 top coats of cellulose paint have been applied. The parts painted in black have also been lacquered to give a hard durable finish. The painting was carried out a year ago so it has been given time to harden off. Where black bolts have been used to secure any black painted parts then these have generally been chemically blackened rather then painted. The majority of the brass items have been lacquered including the pipes and window frames.
The valve gear has been constructed from mild steel and then case hardened and are all fitted with bronze bushes.
There are additional oiling pots on the motion to offer better lubrication. The crosshead slides have a circular design for lubrication rather than the designed diamond pattern as the builder feels this will offer better lubrication.
The boiler blowndown valve and the grate pins are easily located. The frame stretchers and drawbars has been made of thicker material where the builder felt these areas needed to be strengthened. The suspension too has been stiffened after the main build where it was felt that the loco, as designed was a little soft on its springs.
